SPECIFIGATON forming' part of Letters PatentLNo. 709,315, dated September 16, 1902.

Application filed June 26, 1901; Serial No. 66,139. (No model.)

To all whom, t may concern:

Beit known thatLJoHN THORNTON GILMEE,

a citizen of the United States, and a resident is a specific :description f one form of the invention, While the'clailns are definitions of the actualscopethereof.

Reference is to be had to theaccompanying drawings, forminga part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

` Figure lisa side elevationof the apparatus. Fig. 2 is a plan view thereof. Fig. 3 isanenlarged sectional view thereof. Fig. 4 is a detail section showing the mannerof forming the side wallsof the rosin-vat. Fig.

Figs. 7 andS are detail views showing the manner `of fastening the steam-pipes t'o the blanket or strainer shown in Fig. (3, and Fig. Slis a View'of the gate for commandingthe outflow of the rosin.

The rosin vat or kettle comprises an inner wall 10, around which is placeda corrugated jacket 11, the detailarrangement of whichis best shown in Fig. 4. This corrugated jacket forms a steam-space around the kettle or vat and .is provided with a steam-box 1l, running down one side and under the bottoml of the vat, to which box steam is led by a pipe 12 from a suitable `boiler 14 or other source of steam generation. This box serves to distribute the steam throughout the corrugated jacket, whereby to heat the vat. The vapor and water of condensation are led by a pipe 15, passingfrom the lower part of the box 1l, back to the boiler by way of a return-pipe 16. The vat is fitted with a suitable removable i cover 17 and also with a safety-valve'lS of any approved form. JWithin the upper partv o'i the vat is a removable strainer-basket 19,

`of woven wire orother analogous material, in

which the crude gum is placed This basket is sustained by a perforate heat -rack or blanket,7 which is `formed of two parallel plates 20, (see Fig; 6,) havingindentations 2l and connected together by thimbles 22, lo-

' cated attthe said indentations. These thimbles not only fasten the plates together and produce a rigid structure, but also form passages through the blanket. The blanket is suitably sustained from tho walls of the vat 10` and has a space between' the plates 20 supplied with steam by means of pipes 23,com municatingwith the steam-space around the vat or kettle lO. The blanket or heater-rack is provided to apply the rst heat to the gum, while the` thimbles allow the gum to run through the blanket. The pipes 23 are joined to the pipes 24, passing from the blanket, by means of ball-shaped extensions 23%itted in sockets 24. (See Figs. 7 and il.) Said pipes are held together by a stirrup 25, which connects the pipes 23 and 24c and is fastened in Operative'position by a thumb-screw or other analogous device 26. The stirrup ispivoted to the pipe 23 through the medium of pins on a collar 25 on said pipe, so that the stirrup may upon loosening the screw 26 be thrown sidewise to permit the disconnection of the pipes 23 and 2 t and the removal of the blanket, it' desired.

The crude gum placed in the basket 19 is heated by the steam within the blanket, and as it melts it passes through the blanket down into a funnel-shaped partition 27, arranged in and suitably sustained by the walls of the vat 10 and having itsdischarge portion or mouth 2Sprovded with a filter formed of cotton-batting or other absorbent material 29, at the top and bottom of which are woven-wire screens orsieves 30. The gum passing through this ilter falls into the bottom of` the vat l0 and lies over the same, as indicated in Fig. 3. It is also kept in a liquid state by the action of the steam within the jacket 1l.

3l indicates the still, which is surrounded by jacket 32, (see Fig. 6,) having indented portions 33, fastened by rivets 33a or otheriffwise `to vthe walls of the still. This construcf'tion provides a very rigid stilland also forms a"l steam-space for heating the same. Steam fromthe lpipe 12 is delivered to the interior of IOO ' manded by a tubular valve 37, fitted therein and connected with aha'ndle or lever 38, projected outside of the pipen- (See Fig. 9.) By this arrangement eective command of the pipe A36 may be had, and the pipe maybe opened or closed quickly by a Very easy operation-that is to say, by a half-turn of the lever or handle 38. The rosin is withdrawn from i the st ill through a discharge 39, commanded by a valve similar to that shown in Fig. 9. This discharge 39 may be made to deliver into a barrel or other receptacle, as indicated at 40, and a tramway 41 may be provided for carrying these receptacles into and out of position, so as to facilitate the operations. passing through the jacket 32 properly heats the gum within the still, and for further heating the gum I provide a blanket 42, which is similar in structure to ,the blanket 20. (See Fig. 6.) This blanket is connected by pipes 43pwith the space inclosed by the jacket 32. j Leading from the still 3l is the stem 44, which has communicating therewith a gooseneck 45, passing from the vat 10. This gooseneckcarries off from the vat into the stem any vapor which might be generated therein. The stem 44 leads down into the condenser, which may 'be of any formv desired, but preferably comprises a tank 46, in which is contained any desired number of condenser-sections. `These sections are made up each of j two pairs of concavo-convex disks 47, fastened together so as to form a central waterspace (indicated at 48 in Fig. 3) and a marginal vapor-space between the pairs of disks. Leading into said central water-space are a number of pipes or*A tubes 49, which permit the free circulation of water in and out of the said space, thus sufficiently reducing the temperature inthe vapor-spaces and causing the condensation of said Vapor. The condensersections are connected together by means of pipes 50, and from the lowermost section a discharge-pipe 5l passes out of the tank 46 to deliver the turpentine into a suitable receptacle 52, provided to contain the same.

In the use of the apparatus the crude gum is charged into the basket 19, which serves eectively to strain the gum, holding back any chips and any particles of foreign matter that may exist therein. The heat from the rack or blanket liquidates the gum and causes it to flow through the perforations of the racks into the partition 27 and through the filter 29, 30, after which the liquid gum passes into the bottom of the vat 10 and is kept in proper condition by the heat thereof. The gum may be drawn ol'at will through the pipe 27 into the still, where it is boiled, and

The steam form of the concentrated product. The construction of" the jackets 1l and 32, particularly the latter, provides an extremely rigid structure, in addition to providing a steamspace around the vat. By indentingor boss- Any vapors thatV I lthe vapors are carried to the condenser, where they lnay be drawn olf by the pipe 29 in the ing in? and riveting them to the walls of the .4

vat a ribbed 4structureis secured, and .yet sufficient space is allowed between the parts lfor the free circulation ofsteam. The same is true ofthe construction of the blanket 20. This not only produces a perforated steamheated rack, butfit enables such a. device to be constructed very cheaply and in the most durable and rigid manner. The basket 12 `.may be removed from time to time to clean it of the matter retained therein, and the steam heater-rack or blanket may also be removed at will by the device described.

By this apparatus the manufacture of rosin and spirits of turpentine may be carried on in a most economical and eective manner.

Various changes in the form, proportions, and minor details of my invention may be resorted to withoutdeparting from the spirit.
